添加自定义视图在一个循环中引起内存不足的错误 [英] Adding custom view in a loop cause out of memory error

问题描述

我试图多次从XML添加自定义视图到另一个视图在Android的活动。但它会导致内存不足的错误打开和关闭该活动后几次。这里是code：

I am trying to add a custom view multiple times from xml to another view in an android activity. But it causes out of memory error after opening and closing that activity few times. Here is the code:

ImageLoader imageLoader = new ImageLoader(currentActivity.getApplicationContext());
FlowLayout postsLayout = (FlowLayout) findViewById(R.id.tab_posts);
postsLayout.removeAllViews();

for (final Post post : postsData) {



                RelativeLayout profilePostItem = (RelativeLayout) View.inflate(this, R.layout.drawer_item, null);
                ImageView postPic = (ImageView) profilePostItem.findViewById(R.id.post_pic);

                String picUrl = post.getSingleImageURL();

                if(picUrl != null && !picUrl.equals("null"))
                {
                    postPic.setTag(picUrl);
                    imageLoader.DisplayImage(picUrl, currentActivity, postPic, R.drawable.default_item);

                }



                profilePostItem.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View view) {
                        Intent intent = new Intent(currentActivity, PostDetailsActivity.class);
                        intent.putExtra("postID", Integer.toString(post.getPostId()));
                        currentActivity.startActivity(intent);
                    }
                });

                postsLayout.addView(profilePostItem);

            }

和这里是drawer_item.xml

and here is the drawer_item.xml

<?xml version="1.0" encoding="utf-8"?>
        <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"              
                android:layout_width="match_parent"
                android:layout_height="wrap_content"

                >


<ImageView 
        android:id="@+id/post_pic"
        android:layout_width="140dp"
        android:layout_height="140dp"       
        android:background="#FFFFFF" 
        android:src="@drawable/default_user_pic"
    />   


</RelativeLayout>

下面是LogCat中输出：

Here is the LogCat output:

谁能告诉为什么它正在泄漏内存？

Can anyone tell why it is leaking memory?
